PURPOSE:To perform logical shift processing in the same route with addition and subtraction processing by providing a bit shifter in a processing stage of addition and subtraction which are processed on a pipeline basis, and making a shift of <=1 digit. CONSTITUTION:When a right logical shift ...
The arithmetic right shift is exactly like the logical right shift, except instead of padding with zero, it pads with the most significant bit. This is because the most significant bit is the sign bit, or the bit that distinguishes positive and negative numbers. By padding with the most sign...
The shifter can shift both left and right, and by 1 or 8 bit positions, selected by amount. An arithmetic right shift shifts in the sign bit of the number in the shift register (q[63] in this case) instead of zero as done by a logical right shift. Another way of thinking about ...
a运算器负责数据的算术运算和逻辑运算,同时具备存数、取数、移位、比较等功能,它是由电子电路构成,是对数据进行加工处理的部件。 The logic unit is responsible for the data the arithmetic operation and the logic operation, simultaneously has functions and so on balance, fetching, shifting, comparison, it...
The shift is a logical shift if the left operand is an unsigned quantity; otherwise, it is an arithmetic shift.Microsoft SpecificThe result of a right shift of a signed negative quantity is implementation-dependent. Although Microsoft C++ propagates the most-significant bit to fill vacated bit ...
